IMPROVEMENT IN APPARATUS FOR COOLING AND FILTERING LIQUIDS.

Specification forming part of Letters Patent No. 82,651, dated September29, 1868.

To all whom it may concern Be it known that I, DANIEL E. SoMns, ofWashington, District of Columbia, havey invented a new and useful Modeof Cooling and Filtering Liquids 5 and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, which make part of thisspecification, and in which- Figure l represents a vertical section of ahydrant with my improvements attached Fig. 2, a similar section, inwhich a series of horizontal pipes is used as a cooler; Fig. 3, asimilar section, in which the cooler is shown as pointed at its lowerend to facilitate drivin g it into the ground 5 and Fig. 4, a similarsection, in which the supply-pipe passes into and out of the cooler,instead of being connected to it.

The object of my invention is to provide a simple and convenient devicefor cooling and iilterin g water or other liquids; to which end myimprovement consists in connecting the supply-pipe, by which they arebrought to the tap or hydrant from which they are drawn,.to a coolerplaced in the earth,beneath and in convenient proximity Vto the tap orhydrant, and connecting to the mouth thereof a filter, of constructionhereinafter to be described.

In the accompanyingdrawings, which show a convenient arrangement ofparts for carrying out the objects of my invention, A represents ahydrant for streets, and B the supplypipe connecting it with thewater-main. D represents the cooler, which is a metallic vessel of anyconvenient shape, and placed in the earth beneath the hydrant.

The supply-pipe B is connected to the cooler, a two-way cock, d, beingprovided, by means of which the water can be shut oif from the coolerand discharged through the pipe F and spoutf, if deemed necessary, toprevent freezing,'and in cases of repair, &c. The water passes throughthe cooler D into the pipe B', which is connected to its Ifop, and isdrawn olf through the spoilt C.

Anice-boX, G, may be used, if desired, to further reduce the temperatureof the water. This box is placed in the earth above the cooler D, andsurrounds the delivery-pipe B. It is inclosed in an air-tight casing orcasin gs,

which' may be filled with air or charcoal, felt,

or any good non-conductor, to prevent the liquefaetion of the ice.'

The ice is introduced bya suitable opening, and the water which isproduced by melting can be drawn oif by a pipe which connects with thecooler D,and is provided with a stopg v l Salt and ice or otherfreezing-mixture may be used in the ice-box or around it, if desired.

A lter, H, is connected to the mouth of the spout C, for the purpose ofltering the water as it is drawn oft'. This filter is preferably acylindrical metallic vessel of convenient size, provided with twopartitions, hh, perforated for the passage of the water, between whichis placed sponge, pumice-stOne, charcoal, or other suitable poroussubstance. It is connected to the spout C by the bifurcated pipe J,which connects with its upper and lower ends, and is provided with atwo; ayeccl,

J'. by means of which the water/can be admitted eitherto the upper orlower end of the flltr, as desired, and dremlcifby the cock h or L2. Y

From this arrangement it will be seen that the water can be made tocirculate either upward or downward through the iiltering material,preventing the latter from becoming choked or having its effectimpaired. I also place sand, gravel, charcoal, pumice-stone, or otherfiltering material in the coolers, and when they need to be cleansed thecock f should be closed and the cock O opened, thereby reversing thecurrent of water and forcing the sediment out at the latter cock.

Fig. 2 shows a modication of my invention, in which a series of pipes,E, united by elbows in the manner of steam-heating pipes, is eniployedas the cooler D, the water being shut off from the cooling-pipes, whendesired, by the stop-cock d in the same manner as in the preceding case.

Fig. 3 shows the cooler made in conical form, tapering to a point at itslower end, for the purpose of enabling it to be more readily driven intothe earth. In this case the supplypipe B is connected to its upper andthe deli very-pipeB to its lower end but the arrangement may bereversed, if found more convenient.

AIn Fig.-` 4 the supply-pipe passes down into the cooler, having one ormore returns, and is surrounded by water, which is supplied to thecooler by means of the pipe b and cock b'. The cooler is shown madeconical and pointed, as in the former case.

My invention is applicable not only to the cooling and filtering ofWater supplied to hydrants, but also to use in breweries and otherestablishments where the cooling of liquids in a cheap and satisfactorymanner is an important consideration in manufacturing economy.

Soda-fountains may have my improvements applied to them with advantageand at triiiing cost.

When conveniently near to a stream or body of Water the cooler may beembedded therein, instead of in the earth.

From the arrangement of the filter H, it will be seen that thecirculation of the Water may be reversed at pleasure by means of thecock J', enabling the filterin g material tobe cleansed ot' the dirt andsediment which accumulate therein.

The lter can be placed either horizontally or vertically, and thedelivery-cock set upon such portions of its periphery as are found mostconvenient.

Having thus fully described my invention, what I claim therein as new,and desire to secure by Letters Patent, is

1. The supply-pipe B, two-Way cock d, and delivery-pipes F B', with thecooler D, placed in the ground beneath a hydrant or tap, as set forth.

2. The combination of the supply-pipe B, cooler D, delivery-pipe B', andilter H, substantially as described.

3. The supply-pipe B, two-Way cock d, cooler D, and ice-box G,.substantially as described.

4. A cooler tapering` toward and pointed at its lower end, as arrangedin relation to supply and discharge pipes, substantially as herein shownand described.
